I LIKE that idea. Back when I had my 70, I had a "2 meter" amateur radio in the trunk. This was a POS called a "GE transistorized progress line."
I built a little relay control box with 4 push buttons for channel (frequency) control and hid that in the ashtray. Some people thought I was a "narc" LOL
This is the "front mount" version. Mine had been modified into the "trunk mount" version, so there was a small control head up front

I had a neon lamp on a little bracket on the antenna loading coil which would glow purple when transmitting----this was the "hi power" 80 watt version. "It impressed" the CBers LOL
